我添加了模块GCM，它与APPENGINE正确配合使用 . 我已经完成了文档说来注册和接收来自Endpoint的消息 .
现在我不想取消注册设备，我不知道它是怎么做的......任何想法？
我测试了gcm.unregister（）和regService.unregister（Idphone）.execute（）但它不起作用
我试图做一个新的AsyncTask类GcmUnRegistrationAsyncTask扩展AsyncTask {private static Registration regService = null;私有GoogleCloudMessaging gcm;私有上下文;
private static final String SENDER_ID = "892982546498";
public GcmUnRegistrationAsyncTask(Context context) {
this.context = context;
}
@Override
protected String doInBackground(Void... params) {
if (regService == null) {
Registration.Builder builder = new Registration.Builder(AndroidHttp.newCompatibleTransport(), new AndroidJsonFactory(), null)
.setRootUrl("https://myproject.appspot.com/_ah/api/");
regService = builder.build();
}
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
String regId = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regId;
MainActivity.token=regId;
regService.unregister(regId).execute();
gcm.unregister();
} catch (IOException ex) {
ex.printStackTrace();
msg = "Error: " + ex.getMessage();
}
return msg;
}
@Override
protected void onPostExecute(String msg) {
// Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
Logger.getLogger("unREGISTRATION").log(Level.INFO, msg);
Toast.makeText(context, MainActivity.token, Toast.LENGTH_LONG).show();
}
}
我想展示所有设备......
